4.7 Analog and Digital Signal Processing Chain

Please note: description is

preliminary

and subject to change.

Processing Chain Overview and Description

The following diagram shows a simplified block diagram of the camera‘s analog and
digital processing chain. The analog processing chain begins with an analog gain
adjustment, followed by an analog offset adjustment. These adjustments are applied to
the video analog signal prior to its digitization by an A/D converter.

The digital processing chain contains the FPN correction, the PRNU correction, the
background subtract, and the digital gain and offset. Non-linearity look-up table (LUT)
correction is available for the 4k model of camera.

All of these elements are user programmable.

Analog Processing

Optimizing offset performance and gain in the analog domain allows you to achieve a
better signal-to-noise ratio and dynamic range than you would achieve by trying to
optimize the offset in the digital domain. As a result, perform all analog adjustments
prior to any digital adjustments.

1.

Analog gain is multiplied by the analog signal to increase the signal strength before

the A/D conversion. It is used to take advantage of the full dynamic range of the
A/D converter. For example, in a low light situation the brightest part of the image
may be consistently coming in at only 50% of the DN. An analog gain of 6 dB (2x)
will ensure full use of the dynamic range of the A/D converter. Of course the noise is
also increased. Note: To maintain valid LUT calibration, use the

ssg

command.
